Disclaimer
Thank you for purchasing the T31 hand-held remote-control station.Here
referred as T31. Please use it in accordance with local radio control regulations
and read this statement carefully before using it. Once used, it shall be deemed to
endorse and accept all contents of this statement. Please strictly follow this
instruction to install and use the product. The supplier will not bear any legal
liability for any result or loss caused by improper use, installation, final assembly
or modification of the product.
Product precautions
1. T31 as ground terminal（ground unit）is matched with air terminal
（airborne）end to use together.
2.The ground terminal is with built-in 12v battery (3S lithium battery). The
airborne end needs external power input DC7.4-12V(2S-3S lithium battery).
Please power the system in strict accordance with specifications.
3.With improper operation, the aircraft may cause a certain degree of injury and
damage to human and the system, please be sure to pay attention to safety during
use.
4. In order to better serve customers, our R&D team has been upgrading and
optimizing the product. The software and firmware are being upgraded
frequently. There may be incompatibilities between different firmware versions
of ground terminal and airborne . So please check the version of software and

www.chinowing.com
5
firmware and pay attention to our website，ask the supplier for the latest
software firmware and technical support.
5.Basic software and firmware version example：<Parameter Setting
Software>：chinowing remote controller 1.3.0。Ground unit firmware：
TTx31_HW_V1.8__SW_1.0.8_BT_2.4。Airborne unit：V21RX-1.0.4。
6.The software, firmware, drivers and port conversion tools covered in this
manual will be updated from time to time on our website, so please visit our
website to download them, or contact us directly.

use of the product, please contact us or visit our website：www.chinowing.comto
get help with.
Installation Note
1. Be sure to use the spare parts provided by our company.
2. Be sure to install the antennas before power-on to avoid damage to the circuit.
3.Try to make the receiver antenna without obstruction, and the end part of the
antenna is vertically downward without bending, so as to avoid shortening the
communication distance or even failing to communicate due to obstruction.

4.Do not disassemble or refit without permission. If you encounter any problem
that cannot be solved during installation, please contact us directly or
Contact the agent.
5.During installation, keep proper distance between electronic devices to
minimize electromagnetic interference.
Precautions for use
1. Before use, please make sure that all connection wires are fastened reliably
and all components work normally.
2.Please open the <RC Configuration Software> and check whether the channels
are normal.
3.Please check the surrounding environment to ensure that there is no
interference from other devices, otherwise T31 data transmission performance
will be seriously affected.
4.Ensure that the antennas are free from obstacles and bends during use, and stay
away from large metal structural parts as far as possible to avoid communication
obstruction
5. Check the power of the remote control before use. If the <Parameter Setting
Software> shows that power is low, please charge the remote control timely. If
the remote control is turned off, the receiver has entered the state of out-of-
control protection. Stop using it when the battery is too low. Don't rely on the
device's low-power alarm, which is only a precaution and tells you when to
charge.Check the power of remote control every times before you use. It takes
about 3hs to be fully charged.

Remote Control Operation
Remote Control&Computer Power-on and Power-Off
In the process of turning on/off the device T30, please pay attention to the
power button, power indicator and 4 power indicators (25%,50%,75%,100%)
and 5 data link indicators (RS1, RS2,RS3,TX,RX).
1. Long press the power button, the power indicator light is on, and then
according to the speed of the release action of the button to decide whether
the computer is turned on or not.
2.Release the power button after the first short sound of the buzzer. At this time,
the remote control is switched on and the computer is not switched on.
3.After hearing the second short sound of the buzzer, loosen the power button.
After starting up the remote control, the computer will display the starting
interface and start up.
4.After using the computer, the computer can be shutdown through shutdown
interface or the power button.
5.Long press the power button to turn off. In the process of shutdown, if the
system detects that the computer is in the boot state, the system will first shut
down the computer before shutting down the remote control.
When you do not use your computer for a long time, please turn it off in
time to avoid the power consumption.

Channel Monitoring and Calibration
The figure above shows the channel monitoring interface, showing the status of
each channel of the remote control. When the remote control is in the wrong
position or there is a rudder phenomenon, click the red box position in the upper
left corner three times to bring up the option of remote control calibration
function, and calibrate each analog channel.

www.chinowing.com
17
Channel Configuration
Click <Joystick Calibration> to start calibration; toggle all the joysticks and knobs,
includingT1，T2，T3，T4，LW，RW，R1，R2，R3，R4 to ensure that all analog
channels touch the maximum value, the minimum value of stroke and then finally
to the middle position. Click to complete the calibration.
After the calibration is completed, toggle each joystick to see if the parameters
setting software display matches the action to verify that the calibration was
successful. When the R1，R2，R3，R4 knob switches hit the middle position, they
will give a“didi”sound.
The channel display of the remote control is divided into three parts. The left
part shows the output value of SBUS-1, the middle part shows the
corresponding status of each channel, and the right part shows the output
value of SBUS-2. SBUS1 and SBUS2 can be configured separately.

www.chinowing.com

1. Click the channel configuration button. The above picture shows the
configuration interface. SBUS1 and SBUS2 can be configured respectively.
CH01-CH16 channels of each S-BUS are freely compatible with
T1 , T2 , T3 , T4 , LW，RW，R1，R2，R3，R4，F1-F15，S1-S4，UP，DOWN，
LEFT，RIGHT，OK，STOP.Among them, T1, T2, T3 and T4 are the main
joysticks; LW and RW are the returnable middle levers; R1，R2，R3，R4 are
knobs; F1-F15，S1-S4，UP，DOWN，LEFT，RIGHT，OK，STOP are 25 keys.
2. The servo phase can reverse the each channel of the remote control. The
midpoint trimming adjusts the pwm output value for each channel rocker in
the middle position, the adjustment range is from -125 to 125, and the linear
servo stroke amount -31 to 31. The steering stroke can be adjusted from -150
to 150. The default is -100 to 100. Do not adjust if there is no special need.
3.Fail-safe protection settings: click on the small white box, when there is a
<√> in the white small box, the fail-safe protection function of the current
channel works; set the value of the corresponding dialog box, the current
value is the pwm value of the out of control (after setting, please verify by
flight control, ground station or servo).
4.There are three operation modes: American mode, Japanese mode and Chinese
mode
